摘要
目的:研究改良摆型矫治器与上唇挡联合治疗牙列拥挤的临床疗效。方法:选取应用上唇挡联合与不联合改良摆型矫治器治疗替牙晚期或恒牙初期重度牙列拥挤的患者24例,测量矫治前后的X线头颅侧位定位片并进行配对t检验以评估疗效。结果:唇挡结合改良矫治器主要是通过牙齿的移动和牙槽骨的改建,A点的前移,s s-OLP增加2.7mm。上磨牙远中移动3.3mm。结论:改良摆型矫治器可以有效推动磨牙远移,而联合应用唇挡可以促进上颌前部发育、改善患者侧貌外形。
AbObjective To evaluate the treatment effects of upper lip bumper improved reformed pendulum therapy on crowed malocclusion in the beginning of permanent dentition. Methods 24 patients with crowed malocclusion in the beginning of permanent dentition were treated with reformed pendu!um with or not with upper lip bumper,Cephalometric analysis was performed with pretreatment and posttreatment cephalograms. Paired ttest conducted to assess the treatment effects. Results Teech moving and alveolar rebuilding is the main change after the treatment by upper lip bumper and reformed pendulum comparison of only use reformed pendulum.The improvement of overjet is achieved with foreward of A point,ss-OLP increase 2.7mm,and the upper molar was distalized by 3.3mm. Conclusion Upper molar was distalized in the beginning of permanent dentition can be obtained effectively by reformed pendulum.And joint upper lip bumper can improved maxillary anterior development,modify the patient side appearance.
